has thus far elicited multiple suggestions, of which one of the simplest
seems to be to just insert a Text cell (either blank or maybe a caption
or title cell) just before the Output cell you want to keep.
I'm a bit surprised that only one reply suggested or commented on the
even simpler approach pf just changing the style of the Output cell in
the Format >> Style menu . . . namely a reply from "Kevin J. McCann"

I don't know what "Figure" is, or at least don't see any such style in
the Default style sheet. But if my Output cell is a Plot or other
graphic, my experiments also show that just changing the style of an
Output cell to Text (or one of the header styles) does what I want. My
only concern in doing this is that I don't know what other hidden
consequences this may be causing . . . ???
